Question

Quizplus · Accepted Answer

Endorphins are neurotransmitters that act as natural painkillers and are released during high-intensity physical activity, such as running a marathon. They can produce feelings of euphoria and reduce feelings of pain or discomfort. This is likely what allowed Mobombi to continue running despite breaking his leg, and then experience the pain afterwards.
